' My.' vventlon relates particularly to vari-lable connections for typewriting machines,

and has for its main object to provide improved devices of the class specified.

To the above and other ends the invention consists in the features of construction, combinations of devices and arrangements of parts v'hereinafter fully described and parlcated by dotted lines.

ticularly pointed out in the claims.

My invention is shown as' appliedto a4 lvtonarch typewriting machine and to the parts connectingthe universal bar with the dog carrier or rocker, but the nature of thel invention is such that it may be applied to other' forms of writing machines'and may be used toconnect other members besides the universal bar and carriage Vfeeding devices, Whether said other means be in the Monarch machine ior'in other forms or kinds of Writing machines. j y

its upper'end by a link 11 to a type har 12 pivoted in a hanger 13 which is secured by a screw 14 to a segmental type bar support 15 on which the type bar hangers .13 are arranged in segmental series. The type bars are normally sup )orted on a type rest 16 and are adapted, W en suitablyI actuated, to cooperate with the front face of a' rotary platen I 17 mounted in a carrier or carriage comprising side bals 18 and a grooved rear bar 19. Anti-.friction balls 2() cooperate with vthe grooves in the bar 19 and with groovedtrack-ways 21v which are' secured b v screws 22 to standards 23 iixed. to and rising from'the top plate 3. 4A carriage 'leed rack 24 is supported on arms 25 pivoted at 26 to the side bars 18 `of the carrier or carriage.` Said rack 24 normally meshes `with ad'ced pinion 27 which is operatively connected 'with a toothed escapement Wheel 28 coperative with which are fed dogs29 mounted at the top `of afdog carrier orr'cker comprising a vertically disposed arm 30., a rock shaft 3l land a horizontally disposed arm 32. rl`he rock shalt of the dog carrier is pivoted at its ends on ears 33 extending rearwardly `from a supporting bracket 34 which is suitably secured to the frame of the machine. A restoring spring 35 normally maintains the dog rocker in the position shown in Figi. i rThe forward end portion of the dog rocker arm 32 is provided with a curved tread 36. A unlversal bar 37 underlies all of, the. l'iey levers and the spacing levers (not shown), said universal bar being supported on a universal bar frame comprising a roc-k, shalt-'3S having its ends supported on fixed pivots and an arm l) extending rearwardly from the middle ol' the. rock shaft. A coiled restoring spring' li() tends to maintain the universal bar 37 normally in the position shown injFfig. 1.

.The parts thus far vdescribed do not diiier essentially from the corresponding parts of the Monarch.machine and it is notdeemed necessary to describe. them in greaterdetail at thisplace. f

l preler to connect the carriage feeding' device, or dogl rockcr'irith the universal. bar and the universal bar frame'bfr a novel 'connection Vwhich is extensible so' that its dimensions'may be varied to vary the operation of the carriage 'feeding Adevices as compared with the operation ofthe type bars Ior printing mechanism. The novel connection 1s shown in detail in Figs. 2. to` Geinc'lusive and comprises an upper member or bar 41 which has a broad upper end portion 42 terminating in a horizontally disposed ledge or lip 43 which is adapted to coperate with the curved tread 36 of the dog carrier. The member 41 is loosely connected with the arm 32 of said dog carrier by apin and slot connection, being formed below the ledge 43 with a key-hole slot 44 which receives a headed pin or screw 45 secured in the left- .hand face of the arm 32 near Iits forward end. Near its lower end portion the member 41 is provided with a vertically disposed slot 46 and above the slot a pin or stud 47 projects -outwardly from the face of the member, said '-pin or stud being suitably secured to said the pin 50.

member. A lower member or bar 48 is formed at its lower end'with a round hole 49 39 oi' the universel bar frame near the rear' end of said bar (Fig. 1). A. spring clip 51 suitably secured to the arm 39 serves to maintain the member 48 in engagement with The construction is such that the member 48 is detachably and pivotally connected with the universal` barframe. The upper end portion 52 o'l.l the member 48 is widened into a platelike part or plate as shown most clearly in Fig. 4 and is provided with a vertical slot 53. Below said slot a pin or stud 54 projects from the face of the member in an opposite direction to the pin or stud 47 in the upper member. The pin 47 is adapted to engage with the slot 53 in the lower member and the pin 54 is adapted to engage with the slot 46 in the upper member as shown clearly in Figs. 2 and 6. Arranged between the upper and lower members'or bars 41 and 48 is an eccentric member or rotary device in the form of a sheet metal disk 55 which is clearly shown in Fig. 5. The disk is provided with a central perforation 56 and with two cam or eccentric slots 57 and As will be understood from an inspection el' Fig. 5 the distance oi' each of said slots lfrom the center oi.' rotation ol' said disk increases gradually from oneend ol' said slot' An arm or finger piece to the opposite end. 59 extends rearwardly 'from the periphery of the disk 55 and serves as a handle l'o'rn'ianually adjusting the same. A bolt 60 serves as a support for the disk, said `bolt, as is clearly shown in Fig. 6, passing through the slot 46, thence through the central opening 56 in the disk and then through the slot 53, the axis o'lI rotation of the .rotary member or disk being transverse to the length ol' the two part link con'iprising the members 41 and 48. lt Vfurther to be noted that these members are in the nature of plates and that the axis ol the rotary device is at right angles to the laces oi' the plates or members 41I and 48. A nut 61 engages with threads on the end of the bolt 60 and when tightened coacts with the head of the bolt to fasten or clamp the two members or bars 41 and 52-and the disk 55 tightly together and thus maintain them set in adjusted positions. The pin 47 in the upper member engages with the slot 57 in the disk and the pin 54 in the lower member engages with the slot 53 in the disk. As shown in Fig. 6 the member 48 is bent or oil-set as indicated at 48aL so that the body or lower portion oi the bar is in the same plane as in the u per member or bar 4l.

Be 0W the slot 44 the member 41 is provided with a vertical slot 62 which receives a headed screw 63, the latter serving as a support for a line locking member or lug of improved construction, preferably 'formed of sheet metal and comprising an engaging inger 64, a laterally bentcportion 65, aportion 66 parallel with the engaging finger and a short laterally bent portion 67 parallel with the portion 65. The portion 66 with. the portions and 67 at its ends 'forms a U-shaped engaging part which lits over and closely embraces the member or bar 41, the latter at this point being rectangular in cross section.- The line locking member is adapted to be clamped to the bar 41 by a nut 68 which cooperates with the bolt 63. It will be understoodthat by loosening the nut 68 the line lockingy member may be shifted up and down lengthwise of the member 41', the up and down or right line motion being limited by the length of the slot 62. lt will also be understood that rotary motion of the line locking member, that is motion about the bolt 63 as a pivot, will be prevented by the portions 65 and 67 which contact with the edges ol' the member 41. The finger portieri 64 oil the line locking Inember is adapted to coperate with a hook-like device 69 which is part of 'a line locking mechanism like that disclosed in the patent to Felbel, No. 667,928, datedl September 18th, 1900.

It will be understood that when any key lever is o erated it causes a depression o'i' the universa bar i'rame and a lowering of thc eX- tensible or variable connection comprising the bars 4l and 48, the disk 55 and the bolt and nut wh ich normally clamp the members and the disk together making them act in effect as a single piece. The lowering of the connectioncauses the lip or ledge 43 to contact with the tread 36 of the dog carrier, rocking the latter and causing the feed dogs 29 to co-act with the escapement wheel-28 in the usual manner. 'Vhen the. depressed key ler-'er 1s released the dog carrier. is ren stored to normal position by its restoring spring 35, and the universal bar frame and the novelv connection are restored to normal positions by the combined action of the restoring springs 35 and 40. It will further be understood that variation in the operation oi' the dog carrier or rocker will take place according as the lip 43 at the top of the o erator it is only necessar ltentinthe movement of the universal' bar frame, and the printing mechanism `and the `feed'fdogs 29 are moved forward transversely ofthe esca ement wheel 28 a less orgreater distance. rellmmary to adjusting the relation between the'dog carrier and universal bar either initially or to compensate for wear orto suit the particular requirements of the to loosen the c ampi'ng nut 61 suflicienty to permit a manual rotary movement to be communicated to the eccentric device or disk 55. Bymoving the handle 59 of the diskupwardly it will be a parent that the eccentric slots 57 and l58 co erate with the pins 47 and 54 res ectively Io force said pins apart, and as sai pins are fixed to the upper and lower members of the connection it will be clear that said vconnection will be lengthened or extended. The lower member 48 is held from movement by the pin 50 on the universal bar frame and consequently any inin the length of the connection as a whole will result in the upward movement of the ledge 43, causing it to separate to a greater extent from the tread 36 on the dog carrier. Similarly a downward movement of the handle 59 will result in drawing the pine 47 and 54 closer together and in a consetuent lowering of the lip or ledge 43. It wi further be apparent that even when the `clamping nut 61 is loosened the disk 55 will cooperate with the pins 47 and 54 to maintain the upper and lower members in any relation to W ich they may be brought by the rotary movement' of the disk, so that the adustment of tli connection may be tested efore the parts are set or clamped by the tightening of the nut 61.

. The construction above described forms a comparatively simple and at the same time a. very convenient method of regulating the operation of the escapement devices. As has been heretofore stated the invention is not confined however to connecting the devices shown butpmay be employed in other arts of typewriting machines wherever ound convenient Iand useful.

Various changes may bevmade without departing from the spirit and'scope of my invention.

What I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine, the combination of a carriage, carriage feeding dcvices, a key actuated universal bar, and a connection between said universal bar and certain-of said carriagefeeding devices, said connection comprisingtwo slotted members each having a pin or stud cooperative with the slot in the other member, and a rotary adjusting device having eccentric slots` cooperative with the pins of said members to vary'the relationship between said members.
